Changes of the neurological function scores and infarct volume between the young and adult groups (1 and 3 days of reperfusion after 30, 60 and 90 min of ischemia). Neurological Scores (A) (Specific neurological scores are presented in Additional file 2); The infarct volume was determined with TTC staining, and the white area was the infarct area. The infarct volume was expressed as the ratio of (infarct volume/the contralateral non-infarct volume) × 50% (B and C). (n = 7 per group; ^*p < 0.05, significantly different from the respectively sham-group; ^#p < 0.05, significantly different from the corresponding young-group at the same ischemia time; ^$p < 0.05, significantly different from the corresponding 1d group at the same ischemia time; ^&p < 0.05, significantly different from the respectively preceding group at the same reperfusion time.) The bars indicate the means ± SEM
